I'm interested in upgrading to 3.0 either by being added to someone else's dev account or paying for my own. What would make the difference is whether paying the $99 enables you to beta test 3.0 applications like AIM. I'd like to try out the push notifications and other api features but just being on 3.0 firmware with applications made for older firmware won't provide those benefits. Can anyone let me know if being an iPhone developer allows you to beta other apps? Thanks!
